DOOR OPERATOR AND LOCK.

Specification of Letters Patent.

Patented Sept. 10, 1912.

Application filed April 3, 1912. Serial N 0. 688,275.

- freight cars. In practice, from one cause or another, such doorsrepeatedly fail to operate freely as they should. ometimes the runninggear at the top of the door is out of order. Sometimes the door is inbad repair, due to warping, hard usage, or other cause.- In all suchcases, considerable force must be applied both to close and open thedoors.

The main object of the present invention is to provide a closing andopening device which will meet these conditions of service and willpositively open and close the door when desired.

In carrying out my'invention, I employ a lever to apply force to thedoor at the end of its closing movement and at the beginning of itsopening movement. In this way, extra force is applied just when needed.I also provide parts which may be readily and cheaply manufactured andassembled, while at the same time performing all their functionsefiiciently.

The various features and details of my invention, together with theirfunctions and advantages, will be best .understood upon reference to thefollowing'detailed description taken in connection with the accompanyingdrawings, and the scope of the invent-ion will be pointed out in theappended claims.

In the drawings, Figure lis an elevation of a portion of a freight carhaving a door provided with a closing and opening device constructed inaccordance with the present invention; Fig. 2 is a section through aportion of the same taken on a-plane indicated by the line 22 of Fig. 1;Fig. 3 is a perspective view of .thedevlce showing the lever in openposition; Fig. 4- is a section through a portion of the lever and thedoor jamb, taken on a plane indicated by the line 44 of Fig. 1; Fig. 5is a similar section through another portion of, the lever and j amb,taken on a plane indicated by the line 55 of Fig. 1; and Fig. 6 is aperspective view similar to Fig. 3, but viewed in a different direction,of a modified form of the invention.

Throughout these figures, like characters refer to like parts.

Referring to the drawings in detail, 10 designates the body of the carprovided with a sliding door 11, supported by hangers 12 having groovedwheels 13 which engage the track 14 carried by the body 10 at the upperedge of the door opening. A jamb 15 extends vertically along thelefthand edge of the door opening and is adapted to be engaged by theedge of the door when the latter is in closed position.

Guiding brackets'16, 17 are secured to thebody 10 and cooperate with thelower edge of the door 11 in the usual manner. A rubbing strip 18 ofusualconstruction is also provided at the lower edge of the door. Ahandle 19 is secured to the door for the purpose of opening and closingit.

The structure thus far described is that of the usual freight car and ofitself constitutes no part of the present invent-ion.

' In applying my invention to this car structure, I locate the lever20,- by which force is applied to the door at'the end of its closingmovementand the beginning of its opening movement, upon the jamb 15. Itis pivoted upon a pivot bolt 21 which extends through the jamb 15. AWear plate member 22, secured by bolts 23, is located upon the jamb -15so as to engage the rear of the lever 20. This plate is U-shaped andembraces the face and a portion of two sides of the j amb, as moreclearly illustrated .in Fig. 2. Cross bolts 24 unite the lateral flangesof this member 22. The upper end of the lever 20 is provided with anoffset extension 25 which is notched on the left-hand side so as toprovide a hook 26 and a iding lip 27. A hasp 28 is slotted at one en forthe reception of the hook 26 and is loosely ,se-

cured to the door 11 at the other end by a staple 29. Asshown, the haspis twisted so that itsends lie in planes at right angles u to eachother. By this, the hasp may be more readily moved up and down about itsconnection with the door and more readlly engaged by the hook 26, whichis formed upon the offset 25. As illustrated more particularly in Fig.2, the staple 29 s mounted upon a plate 30. At one end, t passes throughan opening in the plate 30 and into a hole 31 in the door 11. At theother end, it is pointed and likewise passes through a hole in plateinto the door 11. The staple 29 and the plate 30 are secured to the door11 by bolts 32 and 33, bolts 32 passing through staple, plate and door,and bolts 33 through the plate and 'door only. The lever 20 is providedwith a projection 34 which extends into the'space between the jamb 15and the door 11. The hook 26 and hasp 28 cooperate in closing the door,while this projection 34 is employedin opening it, as will be explainedmore fully hereinafter. A wear plate 35 is set into the edge of the doorand has a lip which extends around the corner to.its front face. Thisplate is engagedby the projection 34 in the operation of the device andthe lip serves to engage the hasp 28 to prevent its wearing olf thecorner of the door. The lever 20 is provided with a lower hingedextension'36 having a handle 37 at its lower end, an angular projection38 ,and slot 39. The horizontal portion of the projection 38 is providedwith a slot 40, and the vertical portion with a hole 41. When the leveris .in closed position, a staple 42 extends through the-slot 39, and alocking pin 43, connected to the hinged extension 36 by a chain 42,extends through the hole 41 and the opening in the staple 42. An openingin the pin allows a sealing wire or tin 44 to be passed through the pin43 and the slot 40. Its ends are fastened together by the usual seal 45.The staple 42 is formed upon a plate 46 which is similar to the plate 22andissimilarly held in position by bolts 47 passing through the plateand the jamb 15.

In the modified form of the invention, the lever 20' is the same inconstruction at its upper end as the lever 20, but its lower end is bentso as to provide two angular webs 48 and 49. The handle 37, theprojection 38 having the openings 40, 41, andthe slot 39 are the same inconstruction as the corresponding parts in the other figures, but arelocated at the lower end of the web 48 so that they occupy a position atright angles to that occupied in the other form of the invention.Because of this change, staple 42 upon plate 46' is shifted around tothe left side of the jamb 15. When the parts are in closed position, thepin 43 passes through the opening 41' and the opening of staple 42, justas in the other form. I

In operation, the car door 11 is closed by I hand until it approachesthe jamb 15 near enough to allow the slot in thehasp 28 to pass over thebook 26. Then the handle of the lever is grasped and itis drawn aroundto the right and force is thus applied to amb 15.

close the door 11 against the When the parts are in closed pos1tion,-the

projection 34 will lie close againstithe jamb.

15, but when it .is desired to open the door and the lever is moved inthe opposite direction, the upper edge of the projection 34 Will engagethe wear plate 35 on the adja cent edge of the door to force the latteropen. When thus opened, the hasp 28 may be removed from the hook 26 andthe further opening of the door accomplished by hand. When the lever hasbeen moved to locking position, it may be sealed, as before explained.In the one case, the hinged extension of the lever must be moved aboutits hinge so as to freely pass to a position Other applications may alsosuggest themselves to those skilled in the art. I have sought, by theterms of the appended claims, to cover the various applications of myinvention and the possible alterations and modifications, which comewithin its spirit and scope, by the terms of the appended claims.
